Depends on the style you're after. What about using a basic brass garden tap if you're after something a bit industrial? Theres a few different styles and configurations. A local plumber could bend up the gooseneck out of copper as well.

I'll look into that.. Definitely wanting something with clean lines so not sure if a garden tap would suit. Thank you for your suggestion

I'd consider buying a cheap one and sacrificing it every few years. If you give it a spray of vanish you'll get a bit longer. Otherwise Id be looking at marine suppliers but the style choice is likely to be limited.
